It's at 13:54, after the Piko 2-6-2T (the vid is 23:54 long!). Shame they didn't sort the rollers out under the front unit.Tim Brien said:This link from Sinsheim 2014 clearly shows a TL 45 HSB Mallett on a rolling road with the forward motor block certainly faster than the aft block. 23.54 minutes in from the start.
